Wife of suspected NYC bomber discloses conversation on day of explosion near Port Authority

MIDTOWN, Manhattan -- The wife of the man suspected of detonating a pipe bomb in an underground corridor near New York City's Port Authority Bus Terminal said she spoke to her husband on the day of the explosion.

Jannatul Ferdous spoke with ABC News from behind a closed door at her apartment in Dhaka, the capital city of Bangladesh.

She said she talked with her husband, Akayed Ullah, on the phone Monday morning, the day of the bombing in which police said Ullah caused an explosion in the subway tunnel in the name of ISIS.

Ferdous said her husband asked her during a visit to Bangladesh in September to read the writings and sermons of a known radical Muslim preacher.
